Abstract With the advent of Transformer-based convolutional neural networks, stereo matching algorithms have achieved state-of-the-art accuracy in disparity estimation.Nevertheless, this method requires much model inference time, which is the main reason limiting its application in many vision tasks and robots.Facing the trade-off problem between accuracy and efficiency, this paper proposes an efficient and accurate multi-level cascaded recurrent network, LMCR-Stereo.

To recover the detailed information of stereo images more accurately, we first design a multi-level network to challenge gravel grinder update the difference values in a coarse-to-fine recurrent iterative manner.Then, we propose a new pair of slow-fast multi-stage superposition inference structures to accommodate the differences between different scene data.Besides, to ensure better disparity estimation accuracy with faster model inference speed, we introduce a pair of adaptive and lightweight group correlation layers to reduce the impact of erroneous rectification and significantly improve model inference speed.

The experimental results show that the proposed approach achieves a competitive disparity estimation accuracy with a faster model inference jacques marie mage baudelaire 2 speed than the current state-of-the-art methods.Notably, the model inference speed of the proposed approach is improved by 46.0% and 50.

4% in the SceneFlow test set and Middlebury benchmark, respectively.
